Climate change refers to long-term changes in the Earth’s temperature, weather patterns, and climate system.
It is one of the biggest environmental challenges facing the world today.
What is Climate Change?
Climate change means a significant change in average weather conditions over a long period of time, such as:
- Rising global temperatures
- Melting glaciers
- Sea level rise
- Extreme weather events
Main Causes of Climate Change
1. Greenhouse Gases
Carbon dioxide (CO₂), methane, and nitrous oxide trap heat in the atmosphere.
2. Burning of Fossil Fuels
Coal, oil, and gas release large amounts of CO₂ when burned.
3. Deforestation
Cutting trees reduces the Earth’s ability to absorb carbon dioxide.
4. Industrial Activities
Factories and vehicles increase pollution.
Effects of Climate Change
- Global warming
- Floods and droughts
- Loss of wildlife
- Food and water shortages
- Health problems
Solutions to Climate Change
1. Use Renewable Energy
Solar, wind, and hydropower reduce carbon emissions.
2. Save Energy
Switch off lights, use energy-efficient appliances.
3. Plant More Trees
Trees absorb CO₂ and improve air quality.
4. Reduce Waste
Recycle, reuse, and avoid plastic.
Role of Individuals
- Use public transport
- Save water
- Avoid burning waste
- Spread awareness
Conclusion
Climate change is a serious threat, but with collective efforts from individuals, governments, and industries, it can be controlled for a better future.
